单击图像时，IOS segue无法正常工作

Question

I have a view with an Image View, when the user clicks on it, I want to load the image inside it in a separate view.

This is my segue:

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if ([segue.identifier isEqualToString:@"Show Player Information"]){
        if ([segue.destinationViewController isKindOfClass:[PlayerViewController class]]){
            PlayerViewController *playerViewController = (PlayerViewController*)segue.destinationViewController;
            [playerViewController setPlayer:[self.team.players objectAtIndex:self.tableView.indexPathForSelectedRow.row]];
        }
    }else if([segue.identifier isEqualToString:@"Show Image"]) {
        if ([segue.destinationViewController isKindOfClass:[ImageViewerViewController class]]){
            ImageViewerViewController *imageViewerViewController = (ImageViewerViewController*)segue.destinationViewController;
            [imageViewerViewController setImageName:@"France.jpg"];
        }
    }
}

But nothing happens when clicking on the image view though the segue has the correct identifier.

Please check the below screenshot

Could you help me please?

I appreciate your time and efforts.

Regards,

Although it is possible to perform a segue from a UIImageView (although not directly from IB) in my opinion is much simpler to just replace it with a UIButton and set its image instead.

Then, based on your posted code, you could just remove your old segue, ctrl + drag from the button to your destination controller, choose 'push' and then set the segue identifier to Show Image .

It should be noted here that UIImageView (unlike its ancestor UIView ) has its userInteractionEnabled property set to NO by default ( more about it here ). So if you choose to handle any events directly from the UIImageView make sure that you switch it to YES ( here is a similar answer regarding this ).
